Flexible wheel virtual assembly detection device

Abstract

The invention relates to the field of detection devices, in particular, a flexible wheel virtual assembly detection device. It is used to detect the position of a flexible wheel mounting hole. The utility model comprises a measuring body. The measuring body comprises an upper template, a lower template, a plurality of guide posts, a center pin, a plurality of positioning pins and a plurality of latches. A plurality of guide posts is arranged equidistantly on the lower template. The upper template is directly facing the lower template. The upper template is fixed on one end of the guide post. Aplurality of latches is movably arranged equidistantly on the lower template. One end of the latch can selectively pass through the upper template. The center pin is detachably disposed in the middleof the upper template and passes through the upper template. A plurality of positioning pins is arranged on the upper template and on the same circumference as the latches. The flexible wheel virtualassembly detection device adopts a split design different from the traditional integrated pitch gauge, and uses a slip-on latch and a removable center pin, making it not easy to get the part stuck inthe workpiece. Firstly, the positioning holes are used to position the mounting holes and then the latches are used to measure one by one. The specific oversize can be visually determined. It is suitable for large-volume products.

Description

technical field [0001] The invention relates to the field of detection devices, in particular to a flexible spline assembly inspection tool. Background technique [0002] Harmonic reducer is a kind of fixed internal tooth rigid wheel, flex spline and wave generator that causes radial deformation of the flex spline. Harmonic reducer is a new type of transmission structure in gear reducer. With the development of science and technology With the development of the industry, the demand for harmonic reducers is also increasing. Various quality inspections need to be carried out for the flexsplines of the produced harmonic reducers, such as: testing the position of the installation holes of the flexsplines. [0003] The current harmonic reducer industry mainly uses three methods to detect the position of the flexible spline installation hole: [0004] (1) Use sophisticated testing equipment, such as: three-dimensional, two-dimensional and other equipment, to detect the actual siz...

Problems solved by technology

[0004] (1) Use sophisticated testing equipment, such as: three-dimensional, two-dimensional and other equipment, to detect the actual size of the product. The advantage of this type of equipment is that the data is accurate, and it is easy to adjust the machine after detecting a bad flex spline; the disadvantages are: 1. Precision testing equipment is expensive, with large initial investment and high maintenance costs; 2. Precision testing equipment has harsh environmental requirements and cannot be used on the processing site; 3. It is time-consuming to use precision testing equipment to detect workpieces, and it is impossible to fully inspect large batch product

[0005] (2) Using a caliper to measure the hole, the advantages are: direct reading, easy to adjust the machine; the disadvantages are: 1. There are high requirements for the skills of the inspectors to use the caliper; 2. The operation process is complicated and easy to misread

[0006] (3) Using the traditional integrated spacing gauge to detect the workpiece has the advantages of simple use and fast detection; the disadvantages are: 1. It is impossible to find out which hole is out of tolerance, which is not conducive to subsequent machine adjustment; 2. Out of tolerance products are easy to get stuck in the inspection In the tool, it is not easy to take out and easy to scratch the product, and it may squeeze the thin wall when taking out the product to cause its deformation
